PHOENIX -- The D-backs acquired Minor League outfielder Mitch Haniger and Minor League left-hander Anthony Banda on Thursday from the Brewers in exchange for outfielder Gerardo Parra.

Haniger, 23, was ranked as the eighth-best prospect in the Brewers' system by MLB.com and was hitting .255 with seven doubles, 10 homers and 34 RBIs at Double-A Huntsville.

Haniger, who can play center field, is regarded as a patient hitter with decent speed, and he has power potential. He was the 38th overall pick in the 2012 First-Year Player Draft and was a member of the Arizona Fall League's Top Prospects Team last year.

Banda, who turns 21 in a couple of weeks, has appeared in 20 games (14 starts) for Class A Wisconsin and was 6-6 with two saves and a 3.66 ERA.

Parra was hitting .259 for the D-backs this year. He hit .274 and won a pair of Gold Glove Awards during his six seasons in Arizona.

"I try not to think anything about it because I'm happy being here," Parra said prior to Wednesday's game. "I'm happy being with the Diamondbacks. But that's baseball. Today you play and tomorrow you could play for another team. But I don't want to think about it and put pressure on myself. I'm going to play hard today and play to win."
